Removing single list item from duplicates

[The creature]

Hi

I'm having an issue with Listboxes. I have a listbox that can have multiples duplicate items. The issue is I want to remove a selected item from the listbox, but as expected it's removing all duplicates of that name.

Is there a way to just remove a single duplicate entry?

My code follows:

Code: ags

String EquipTool1 = ListBox_Toolbox.Items[ListBox_Toolbox.SelectedIndex];
    if (EquipTool1 == "Crowbar")
    {
      int i = 0;
        while (i < ListBox_Toolbox.ItemCount)
        {
          if (ListBox_Toolbox.Items[i] == "Crowbar")
          {
            bD0_Tool1.NormalGraphic=439;
            diver0_tool1=2; // Crowbar
            ListBox_Toolbox.RemoveItem(i);
            ListBox_Toolbox.InsertItemAt(0, "Unequip");
          }
        i++;
        }
      return;
    }

As described in my question, if there are multiple Crowbar items in the list it obviously removes all crowbar items.

Any help would be greatly appreciated in this matter.

Can't you just do something like this (untested) ?

Code: ags

String EquipTool1 = ListBox_Toolbox.Items[ListBox_Toolbox.SelectedIndex];
if (EquipTool1 == "Crowbar")
{
  bD0_Tool1.NormalGraphic=439;
  diver0_tool1=2; // Crowbar
  ListBox_Toolbox.RemoveItem(ListBox_Toolbox.SelectedIndex);
  ListBox_Toolbox.InsertItemAt(0, "Unequip");
  return;
}

You already have the index of what is selected, so I don't think you need to search for it.

I tried that but was presented with this error:

ListboxRemove: invalid listindex specified.
I was curious if it was because it was removing an item that was currently selected so I tried adding: ListBox_Toolbox.SelectedIndex=-1; as that has sometimes caused issue in the past. But no avail. And it's just dawned on me that my unselecting it ListBox_Toolbox.RemoveItem(ListBox_Toolbox.SelectedIndex); wouldn't work anyway...but it didn't work before either.

Code: ags

   if (EquipTool1 == "Crowbar")
    {
      int i = 0;
        while (i < ListBox_Toolbox.ItemCount)
        {
          if (ListBox_Toolbox.Items[i] == "Crowbar")
          {
            bD0_Tool1.NormalGraphic=439;
            diver0_tool1=2; // Crowbar
            ListBox_Toolbox.SelectedIndex=-1;
            ListBox_Toolbox.RemoveItem(ListBox_Toolbox.SelectedIndex);
          }
        i++;
        }
      return;
    }

That is still in a while loop though. I'm suggesting that you remove the while loop.

Yeah that works great!

I'm now not even sure why I was having all that in a loop to be honest. works a charm.

Thank you!
